Models using in XRT Renderer

Models using in XRT Renderer

XRT Renderer is great for researchers, I am also researching about motion blur, so I have downloaded some models such as: ben, hand. However, they are in "obj" format and it does not contain any animation information. I just want to ask you that how you can create animation from those models, which just have many poses like ben_00.obj, ben_01.obj

Thank in advance.

I did very simple things: render each pose and make a movie out of the pictures. There is no motion blur.
To add motion blur would require to interpolate between two successive poses: with the models you downloaded, this is quite easy because each pose contains the same number of vertices in the same order. You just have to perform linear interpolation between vertices. This is called deformation blur and is not supported by XRT.

Thank you for the reply. I just create an index buffer and vertex buffer after loading a 3d models (using Assimp) for rendering in DirectX 11. For linear interpolating vertices, I am not sure that all vertex orders are the same, and there are some problems with 3d models downloaded from "The Utah 3D Animation Repository" such as: ben, hand, and fairy forest. All modesl in obj format, I need to convert to X format with "Ben" model before rendering because there are some wholes if I load and render in obj format :(. Besides, "Hand" model does not have mtl file as well as textures.

Could you give me "Hand" model's mtl file and its textures, please?. Thank in advance.

They are available from "The Utah 3D Animation Repository" in this archive.

Thank for the reply, I downloaded again from the link, but there is still no mtl and textures file :(

Err… I am checking right now the archive (which I got from here): it does contain a hand.mtl, a hand.ppm and 44 hand poses.
